When the light switch is in this position, the rear fog lamp is turned on.

When the 1 light switch is in this position, the rear fog lamp is turned on.

Correct. The direction to the left is the front fog light, and the direction to the right is the rear fog light, so the rotation will screw to the position of the rear fog light.

The rear fog lamp, like the front fog lamp, is actually turned on in the case of heavy fog or low visibility, but the function of the rear fog lamp is to warn the rear vehicles, so the rear fog lamp will emit stronger red light than the brake lamp, which has stronger penetration and still has certain recognition in bad weather.

2 Precautions for using fog lamps

Fog lamps are suitable for bad rain, fog, snow or dusty weather. Fog lamp visibility is about 100 meter. When the visibility is lower than 100 meters, you must turn on the fog lights and pay attention to slowing down.

The main function of automobile fog lights is to let people behind know the vehicles in front. The rear fog lamp is designed to be red for warning. The lighting of the front fog lamp is not omnipotent. If the visibility is less than 30 meters, the function of turning on the front fog light is not too great. At this time, it is necessary to pull over and turn on the danger warning light.

What is the reason that the lighting is not working properly?

The reasons for abnormal lighting work are: damaged light bulb, blown fuse, damaged switch or relay, line fault, etc. During fault diagnosis, the circuit should be checked according to the circuit diagram to determine the fault location.

When analyzing the headlight fault, we should make full use of the fault test results and combine the working principle of the headlight to analyze and judge. It is not difficult to draw the conclusion that there is an open circuit fault in the headlight grounding circuit. After the doubt of the fault is clear, the fault can be eliminated quickly. If the headlight high beam suddenly darkens and is not focused, even if the dimmer switch is turned to the low beam, the high beam indicator on the instrument panel will still light up, and the headlight of the whole vehicle suddenly loses control, indicating that the low beam filament has been burnt out and connected in series with the high beam filament, and the headlight bulb should be replaced.

The function of the lamp is:

1. The main function of low beam and high beam is for night lighting. Low beam lamps are used for urban roads with street lamps, and high beam lamps are used for roads without street lamps or suburban roads such as expressway.

2. The width indicator is mainly used to display the width and length of the car body at night to remind other vehicles and pedestrians to see themselves clearly. When the rearview mirror can't see the road behind the car clearly, it is necessary to turn on the width indicator to increase the driving safety;

3. Daytime running lights In order not to increase the load of the battery, it is not advisable to turn on the headlights during the day. This kind of daytime running light is specially used to remind other vehicles and pedestrians to pay attention to safety during daytime driving.

4. The turn signal can be used for 24 hours to remind other vehicles or pedestrians to turn. In general, turning, merging and double flashing lights in emergency situations are all realized by them, which emit yellow and regular flashing lights to remind other vehicles and pedestrians to pay attention to safety.
